It's my first time growing tobacco, or anything for that matter. I just came back from a little vacation and noticed my plants had flowerheads. I pinched them off, but how far down The plant should you cut it? My tobacco is also very uneven in size due to bad fertilization (until someone gave me the tip to use calcium nitrate wich made all plants starting to grow again.).

I'll attach a few pictures on how it looks and maybe you veterans can give me a few tips.
